论文摘要

由于其在崎rough的地形中的高移动性和遍历性,四倍的平台已成为一个积极的研究主题。但是,确定机器人是否可以通过裂缝环境以及如何准确计算其路径是高度挑战。此外,计算出的路径可能会穿过具有动态物体或环境对机器人或周围人危险的区域。因此,我们提出了一种新颖的概念方法,即通过虚拟现实(VR)中的用户指导路径计划进行教学四倍的机器人导航。我们的系统包含全球和本地路径计划者,使机器人可以通过学习的迭代来生成路径。 VR接口允许用户与环境进行交互,并在具有挑战性的情况下协助四足机器人。比较实验的结果表明,人与路径计划算法之间的合作可以使算法的计算速度平均提高35.58%,并且在测试方案中,路径长度(平均6.66%)的非严格增加(平均6.66%)。此外,用户将VR接口描述为不需要物理需求(10中的2.3),并且高度评估了其性能(10中的7.1中)。寻找一条不太最佳但更安全的路径的能力仍然需要在混乱和非结构化的环境中导航的任务。

Quadruped platforms have become an active topic of research due to their high mobility and traversability in rough terrain. However, it is highly challenging to determine whether the clattered environment could be passed by the robot and how exactly its path should be calculated. Moreover, the calculated path may pass through areas with dynamic objects or environments that are dangerous for the robot or people around. Therefore, we propose a novel conceptual approach of teaching quadruped robots navigation through user-guided path planning in virtual reality (VR). Our system contains both global and local path planners, allowing robot to generate path through iterations of learning. The VR interface allows user to interact with environment and to assist quadruped robot in challenging scenarios. The results of comparison experiments show that cooperation between human and path planning algorithms can increase the computational speed of the algorithm by 35.58% in average, and non-critically increasing of the path length (average of 6.66%) in test scenario. Additionally, users described VR interface as not requiring physical demand (2.3 out of 10) and highly evaluated their performance (7.1 out of 10). The ability to find a less optimal but safer path remains in demand for the task of navigating in a cluttered and unstructured environment.
